The Taxpayer Times

The Framework Most People Get Wrong

Military Tax Returns Are Not Routine Filings

Military tax returns are often treated as routine filings. At a glance, that assumption seems reasonable. A Form W-2 is issued, income is reported, and the return appears no different from any other wage-based filing.

In practice, that assumption is where many returns begin to go wrong.

The most common misunderstanding is simple: taxes are assumed to follow where the taxpayer lives. For military personnel, that is often not the case.

Residency Does Not Follow Duty Station

A service member’s tax situation is not determined by where they are stationed, but by their legal residence – commonly referred to as domicile.

A taxpayer may live in Virginia, be stationed in Virginia, and still not be a Virginia resident for tax purposes. While this may seem counterintuitive, it reflects how military residency rules are designed to function.

The duty station is considered a temporary assignment, even if it lasts for several years. By itself, it does not establish tax residency.

What Domicile Actually Means

Domicile is a legal concept. It refers to the state a taxpayer considers their permanent home.

For military personnel, this is often:

• the state they entered the service from, or
• the state they intend to return to after service

Unlike civilian taxpayers, service members do not automatically change residency each time they relocate under orders. Their legal residence can remain unchanged across multiple assignments.

This stability is intentional – but it is also where many tax returns are misunderstood.

Why Residency Determines the Entire Return

State income tax is based on residency. If residency is not identified correctly, the return can be structured incorrectly from the beginning.

This can lead to:

• filing in the wrong state
• reporting income to a state that should not tax it
• paying tax that was never owed

These are not minor technical issues. They affect the foundation of the return.

Why the Return Looks Normal – Even When It Isn’t

One reason these errors are common is that the return itself does not appear unusual.

On the surface, everything looks familiar:

• a W-2 reporting wages
• an address reflecting current residence
• standard inputs in tax software

However, several elements can be misleading if taken at face value:

• The address on the return does not determine residency
• The state listed on the W-2 does not control taxation
• The duty station does not establish a filing obligation

Because the form looks ordinary, the underlying issue is often overlooked.

Most Errors Are Structural, Not Technical

Errors in military tax returns are rarely about calculations.

They result from applying the wrong framework.

A common situation involves a service member stationed in Virginia whose return is prepared as a Virginia resident return. State tax is paid accordingly, even though the taxpayer may not have been a Virginia resident at all.

This is not a calculation mistake. It is a misunderstanding of how residency works.

Why These Mistakes Go Unnoticed

These issues often go undetected because nothing appears wrong.

The return is filed. The numbers calculate correctly. The tax is paid.

Tax software does not always flag residency issues, and taxpayers generally assume the result is accurate. Without a clear understanding of the underlying rules, there is little reason to question the outcome.

The One Question That Comes First

Before considering deductions, credits, or tax-saving strategies, one question must be answered:

What is the taxpayer’s legal residence?

Everything else follows from that answer.

If this question is answered incorrectly, the rest of the return – no matter how carefully prepared – will also be incorrect.

What Comes Next

Understanding residency is the starting point.

In Part 2, the focus will shift to how these rules apply in practice, including:

• multi-state filing situations
• military spouse income
• common errors that lead to unnecessary taxation

Military tax returns are not complicated because of the forms involved. They are complicated because the underlying assumptions are different.

Recognizing that difference is what allows the return to be prepared correctly.
